Definitions

  • the invention relates to an adhesive tape, preferably for wrapping elongate material such as in particular lines or cable harnesses with a textile carrier and with a pressure-sensitive adhesive coating applied at least on one side of the carrier. Furthermore, the invention relates to the use of the adhesive tape and a cable harness, which is coated with the adhesive tape according to the invention.
  • bundles of a plurality of electrical leads are wrapped prior to installation or in the already assembled state, in order to reduce the space requirement of the bundle of cables by bandaging and to additionally provide protective functions.
  • film adhesive tapes With film adhesive tapes, a certain protection against liquid access is achieved, with airy and voluminous tapes based on thick nonwovens or foams as a carrier to obtain damping properties, when using abrasion-resistant, stable substrates a protection against scouring and rubbing is achieved.
  • the DE 44 42 092 C1 describes such a nonwoven-based adhesive tape coated on the back of the backing.
  • DE 44 42 093 C1 is based on the use of a nonwoven as a carrier for an adhesive tape, which is formed by the formation of meshes of the fibers of the nonwoven reinforced cross-fiber fleece, so a known to those skilled under the name Malivlies fleece.
  • the DE 44 42 507 C1 discloses an adhesive tape for cable bandaging, but it is based on so-called Kunit or Multiknitvliesen.
  • the nonwoven used according to the invention is a spunbonded nonwoven made of polypropylene, which is thermally bonded and embossed with the aid of a calender, the embossing roll having an embossing surface of 10% to 30%, preferably 19%.
  • Adhesive tapes are known on the basis of a solidified with air and / or water jets nonwovens.
  • WO 99/24518 A1 describes an adhesive tape, wherein the carrier material is a nonwoven, which finds a suitability for the use of adhesive tapes only by the specific selection of fibers or filaments having a fineness greater than 15 denier and by an additionally extruded film layer.
  • EP 1 000 992 A1 describes a perforated cotton fleece with a 10 to 45 micron thick polyethylene coating and an additional release coating.
  • the texturing of thread material is primarily used for textile fabrics made of chemical fibers such as polyester or polyamide in order to give the synthetic fibers a natural fiber-like character.
  • Chemical fibers differ in the Spinning into yarns of natural fibers in the length of the filaments to be spun. The filament length is much shorter for natural fibers than for man-made fibers and is only a few centimeters. In the spinning of short filament lengths to yarns and threads such as cotton this gets through the protruding filament ends a lumpiness and thus a pleasant to the touch. In contrast to this, in the case of chemical fibers continuous filaments are used which, after being spun into yarn, have a parallel position relative to one another and give the yarn a smooth, unnatural ability to touch.
  • the texturing of filament material from continuous filamentary filaments can, for example, be carried out by the deformation of the filaments from their parallel position by torsion or bending with subsequent heat-setting.
  • An example of this is the so-called false-wire method [Fundamentals of Textile Finishing ", 13th Revised Edition, Deutsch subuchverlag 1989].
  • textile fabrics made from chemical fibers such as polyester with textured yarn material, are used, for example, as a front fixation in the high-quality outerwear sector due to their pleasant feel for clothing purposes.

  • a commercial sound meter for example Type 2226 from Bruel & Kjaer.
  • For the human ear are particularly relevant frequencies in the range of 2,000 to 5,000 Hz.
  • the attenuation is given as the difference between the zero value with un-wound steel bar and the respective measured value in dB (A).
  • the noise attenuation behavior is measured by the method set out in LV312 "Automotive Cable Harness Adhesive Tapes" (1/2005).
  • the LV312 "Adhesive tapes for cable harnesses in motor vehicles” (1/2005) is a standard that is used as a common test guideline by the companies Audi, BMW, Daimler and VW.
  • this guideline describes, for example, test methods for the compatibility of adhesive tapes with electrical vehicle cables, as well as for chemical resistance, noise damping behavior, fogging behavior and abrasion resistance.
  • the object of the invention is to provide an adhesive tape, which fulfills the required properties of damping in the sheathing of, for example, cables, which ensures a sheathed product, that is to say in this case a wiring harness, which is more flexible than the previous products, which the known adhesive tapes have been sheathed.
